The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Identification of structural changes in CaCu3Ti4O12 on high energy ball milling and their effect on photocatalytic performance
No full textThe perovskite CaCu3Ti4O12 is known for its ability to photocatalytically degrade model dye molecules using visible light. The influence of ball milling preformed CaCu3Ti4O12 on the catalysts structure and performance in the degradation of rhodamine B and the antihistamine cetirizine hydrochloride, which does not absorb light in the visible region, was investigated. The surface area of CaCu3Ti4O12 increased from 1 m(2) g(-1) to >80 m(2) g(-1) on milling with a retention of 96% CaCu3Ti4O12 phase purity, as determined by X-ray diffraction and extended X-ray absorption fine structure analysis. Multiple characterisation techniques showed an increase in structural defects on milling, including, for the first time, X-ray absorption near edge spectroscopy which showed changes in the local electronic structure from the perspective of Cu and Ti. Photocatalytic degradation was notably higher with the milled sample than that observed for the as-synthesized sample, even after normalisation for surface area, with a doubling of surface normalised rate constant from 4.91 x 10(-4) to 9.11 x 10(-4) L min(-1) m(2) for rhodamine B degradation and a tripling for cetirizine hydrochloride degradation from 2.64 x 10(-4) to 7.92 x 10(-4) L min (-1) m(-2). The improvement in catalytic performance can be correlated to the defects observed by X-ray absorption spectroscopy
Language Change and SA-OT: The case of sentential negation
No full textSimulated Annealing for Optimality Theory (SA-OT) updates Optimality Theory by adding a model of performance to a theory of linguistic competence. Our aim is to show that SA-OT can contribute to language change simulations. Performance "errors" are considered to be one of the causes of variation and change. We have chosen to model the evolution of sentential negation (SN). The descriptive background adopts Jespersen's Cycle, according to which the evolution of sentential negation follows three main stages (1. pre-verbal, 2. discontinuous, and 3. post-verbal). Therefore, we advance a novel model for SN, based on SA-OT. It reproduces the three pure and the two observed mixed stages, whereas it correctly predicts the lack of an intermediate stage between 3 and 1. The success of the approach corroborates the computational, performance-based approach to the data. Finally, we employ the iterated learning paradigm to reproduce historical changes in a "simulated corpus study". This enterprise turns out to be more difficult than one would naively believe.Appeared open access as: Computational Linguistics in the Netherlands Journal (CLIN), vol. 1 (2011), pp. 21-40, and is available at http://www.clinjournal.org/sites/default/files/Lopopolo.pdfA.

Stakeholder research CoVE Water SA: CoVE Water SA the umbrella for all stakeholders
No full textThe water and sanitation sector faces well-documented issues that are challenging to address, leading to the establishment of the Platform of Vocational Excellence (PoVE) Water. This platform brings together five regional Centers of Vocational Excellence (CoVE) Water in Europe and South Africa to ensure high-quality skills and competencies in the water sector. These CoVEs facilitate collaboration among stakeholders, enabling the development of vocational education and training programs to increase awareness, responsiveness to industry needs, and address sector challenges. A few months ago, CoVE Water SA was established in South Africa to achieve the previously mentioned goals. Therefore, it is important that the following research question is answered in this initial set-up phase: What actions need to be taken to enhance the effectiveness of the CoVE Water SA? To answer this research question, several important stakeholders were interviewed. Subsequently, the interviews were analysed thematically in order to extract the most important themes and quotes, PI grids were created to assess power and interest dynamics among stakeholders, and a Social Network Analysis was conducted to understand the CoVE Water SA network and potential clusters.The research findings have unveiled key aspects for enhancing the effectiveness of CoVE Water SA. The current network in the water sector has a low density, implying that many collaborations are lacking. This leads to a high degree of interdependence within the network, resulting in a non dynamic system. The lack of collaborations, such as connections with TVET colleges, schools, farmers and local communities, results in a lack of knowledge, funding and connection to the labour market. Governmental stakeholders, like DWS, EWSeta, and BGCMA, have been identified as influential players with extensive networks and important resources, Local Authorities and Research Organizations also play important roles. Universities exhibit substantial international links, making them crucial contributors. These stakeholders have the potential to provide knowledge, collaboration, and power. These are valuable insights for CoVE Water SA, fostering network growth and effectiveness in the water sector. Furthermore, six key themes have been derived from the conducted interviews, addressing the needs of stakeholders and where CoVE can make a valuable contribution. These themes include raising awareness, reducing the skills gap in the water sector, fostering international collaborations, mitigating the labour shortage in the water sector, improving education material and establishing desired collaborations. For each theme, the interviewed stakeholders have presented their views and numerous suggestions on how CoVE Water SA can assist in addressing these issues. Additionally, stakeholders have also mentioned possible failures of CoVE Water SA, which can aid in preventing any shortcomings of the platform. Furthermore, stakeholders mentioned ongoing initiatives related to the six themes, through which they can contribute to the platform. From the Thematic Analysis, PI Grids and the SNA, a set of actions have emerged that are essential for enhancing the effectiveness of CoVE Water SA. These actions revolve around expanding and enhancing the network, organising activities and contributing to educational improvement. In terms of broadening and strengthening the network, the platform should focus on enhancing the collaborations among educational groups, building stronger relations with international institutions in Europe and Africa, involving TVETs and schools within the water network, improving stakeholder involvement and encouraging the involvement of Local Communities to increase awareness and knowledge about water issues. Furthermore, CoVE Water SA should play a role in organising activities to raise awareness of Water Resource Management. Additionally, it should assist in improving curricula, supporting students’ preparation for the workforce and making the education more practical instead of only theoretical. CoVE Water SA should also provide training and learning resources as well as comprehensive courses.However, this study recognizes several limitations that should be considered in future research and when implementing recommendations for CoVE Water SA. These limitations encompass factors like a limited scope due to resource and time constraints, minimal varied interviewee responses, and potential biases in responses. Addressing these limitations will be crucial in guiding future research and actions for CoVE Water SA.CEGM3000Civil Engineerin

A-t-on besoin des concepts intersémiotiques ? Exemple du hors-champ
No full textInternational audienceAccounting for the broad application of visual studies terminology within literary criticism in recent decades, this paperanalyses the conditions that necessitate an appeal to such intersemiotic concepts. Formalized in an identifiable field,every intersemiotic concept immediately escapes from its starting basis, testifying to the heterogeneous and porousnature of the latter. The intersemiotic concept, therefore, transgresses material divisions: it allows for an approach thatrenders the specificity of the media at stake, without advocating their limits. I test this hypothesis through the specificexample of the hors-champ, what I refer to as the out-of-field, from film’s origins through its contemporary transmedialpotential.Partant du constat de l'application abondante de la terminologie issue des études visuelles dans le champ critique littéraire ces dernières décennies, l'article se propose d'analyser les conditions qui rendent possible et même nécessaire le recours à de tels concepts intersémiotiques. Formalisé dans un domaine identifiable, un concept intersémiotique échappe aussitôt à son ancrage de départ, témoignant à la fois de l'hétérogénéité intrinsèque et de la porosité de celui-ci. Le concept intersémiotique dépasse ainsi la séparation des matériaux : son utilisation peut donc assurer une approche qui rende compte de la spécificité des média en jeu, sans toutefois se cantonner aux limites de chacun. Cette hypothèse sera illustrée, dans la seconde partie de l'article, avec un exemple précis, le concept de hors-champ, depuis sa genèse cinématographique jusqu'à sa portée transmédiale
